ABSTRACT:
A weft yarn feeding device includes a feed roller which rotates at a circumferential speed equal to a running speed of a weft and a pinch roller which moves in and out of contact with the circumference of the feed roller with the weft in between. The rollers are provided between a length measuring device and a main nozzle for injecting a fluid. Upon commencement of feeding of the weft, the feed roller and the pinch roller are brought into mutual pressure contact to positively feed the weft toward the main nozzle. Further, the feed roller surface has a large frictional coefficient and the pinch roller surface has a very small frictional coefficient.
